What is ORIGIN up against—?! Having destroyed DA, ORIGIN is suddenly ambushed by the murderous robot's compatriots SON and GON in what is clearly an act of revenge. But with neither sentiment nor ego, no robot should engage in such illogical behavior—can one among his foes truly be a robot with emotions?! Even as this desperate battle plays out in the shadows, ORIGIN has another fight on his hands: the struggle to pass as human in his day-to-day existence!

Volume 2 of the ORIGIN manga series by Boichi.
